I'm nearly halfway through Red Dead Redemption's story-mode, but for some reason, I can't get into it with the same eagerness as a GTA IV. I'm not sure if the sprawling, unpopulated landscape has something to do with it, because judged on its merits alone, it's surely one of the best game's I've ever played.
I did spend about three hours killing animals and skinning them for money. And there are many design elements that trump GTA IV completely. Being able to save on-the-fly (by way of a campsite) is also a nice idea, and Red Dead Redemption really does feel like a thought-out, well-planned game.
Perhaps I'll re-read Cormac McCarthy's No Country for Old Men, which might induce me to play the game more eagerly. As it stands though, it's a brilliant game with little to fault, but just not as engaging or absorbing as the Ballad of Gay Tony, which I completed recently.
